Gentry General Engineering, Inc., the lowest <br />responsible bidder, in accordance with the base bid in the amount of $805,829, for <br />construction of the Willard Neighborhood Sewer Main Improvements Project, for the term <br />beginning upon execution of the contract and ending upon project completion, and authorize <br />the City Manager and the Clerk of the Council to execute the contract subject to non - <br />substantive changes approved by the City Manager and the City Attorney. <br />2. Approve the Project Cost Analysis for a total estimated construction delivery cost of <br />$1,047,579, which includes $805,829 for the construction contract, $120,875 for contract <br />administration, inspection and testing, and a $120,875 project contingency (approximately <br />15% of the construction contract amount), to be paid with Sanitary Sewer Capital funds. <br />DISCUSSION <br />To determine sewer main pipeline replacement priorities, Public Works staff monitors pipeline <br />condition by assessing critical factors such as history of pipeline breaks, pipe size, alignment, <br />location, and system redundancy. The existing 6-inch-diameter vitrified clay sewer main pipes <br />located in the Willard Neighborhood, installed in the 1920s, are deteriorating, lack of capacity, <br />and have been identified for priority replacement (Exhibit 1). <br />The Willard Neighborhood Sewer Main Improvements Project will install approximately 2,600 <br />linear feet of new 8-inch polyvinyl chloride sewer main pipes, sewer laterals, and sewer <br />manholes. Once this project is completed, the improved sewer system will eliminate sewer main <br />obstructions, prevent sewer overflows, and reduce sewer maintenance requirements. <br />23B-1 <br />
